Plant genetics research. Plant biotechnology researcher holding a culture of Drosera rotundifolia, a carnivorous plant that is being grown in-vitro to study its digestive fluids. This research involves producing human recombinant proteins with medical applications, based on the natural proteins produced by carnivorous plants. The protein being studied here is beta-glucuronidase (GUS). This research is being carried out for PATsas, a French biotechnology company.
